Add Read More link next to customized excerpt

I’m trying to add a Read More link next to the excerpt, and I see that the theme I’m building on has changed excerpt_more to path_excerpt_more.

But when I try to use that like this:

<div class="entry-summary">
	  <?php the_excerpt(); ?><?php path_excerpt_more(); ?>
</div>

…no Read More link appears. What else do I have to do to get the link to print?

I also tried hard coding it in, but the link refers back to the homepage, rather than connecting to the blogpost’s URL:
<?php the_excerpt(); ?><a href="<?php get_permalink($post->ID) ?>">Read more</a>

We’re not using <!–more–> to create the excerpt, but rather the excerpt meta box on the post page, if that makes a difference.

Thanks!
